You went to a therapist or psychiatrist, and the insurance company sent a letter that says no. A denial isn't the end of the road, and you have the right to push back.
Mental health insurance coverage is protected by federal law. When a plan denies your therapy or psychiatry visit, that decision can often be reversed. Below is why these denials happen, what the law actually guarantees you, and the exact steps to appeal.
Why mental health coverage gets denied
Denials rarely mean your care wasn't real or needed. More often, they come from specific gaps in how plans handle behavioral health (mental health and substance use care).
Narrow networks. Your plan's provider directory may list dozens of therapists who aren't actually taking patients. Researchers call these "ghost networks." When one state's attorney general surveyed nearly 400 listed mental health providers, 86% were unreachable, not accepting new patients, or not actually in network. If you end up seeing someone out of network because no one in network could see you, the claim often gets denied or paid at a lower rate.
"Not medically necessary." This is the phrase plans use most to deny therapy and psychiatry. The insurer decides your care didn't meet its internal criteria for being medically needed. Behavioral health gets checked for medical necessity far more closely than a broken arm ever would. The process for getting approval for mental health services can be more restrictive than for medical services. That's exactly why so many of these denials are worth appealing.
Visit caps and prior authorization. Some plans limit how many sessions they'll cover, or require approval before each one. When those limits are stricter than what the plan applies to physical care, that's not just frustrating. It may break the law.
What mental health parity law actually guarantees
Here's the part most people never hear. The Mental Health Parity and Addiction Equity Act (MHPAEA), a federal law passed in 2008, requires health plans that cover mental health and substance use care to do so no more restrictively than they cover physical care. In plain terms, your plan can't make therapy harder to get than a knee replacement.
That means copays, deductibles, and visit limits for mental health can't be tougher than the ones for medical and surgical care. It also covers the quieter tools plans use to say no, like prior authorization and how they build their provider networks.
So why does it still get ignored? The law is easy to state and hard to enforce. Plans comply with the simple parts, like matching copays, but struggle with the complex ones, like network design and how they decide what's medically necessary. The provider shortage makes it worse. Federal workforce data shows that about 40% of Americans live in a Mental Health Professional Shortage Area, so even a plan following the rules can leave you with no one to see.
Mental health parity is real on paper and uneven in practice. That gap is where your appeal comes in.
What to do when your therapy coverage is denied
A denial is a starting point, not a verdict. Here's how to respond, in order.
- Get the exact denial reason in writing. Find your Explanation of Benefits (EOB) or denial letter. Look for the specific reason and the code next to it. "Not medically necessary" and "out of network" lead to different appeals, so you need the actual words.
- Request the criteria they used. You have the right to ask your plan for the clinical criteria behind the denial. Call the member number on your card and ask for the medical necessity criteria and the plan's written reason. Get a reference number for the call.
- File the internal appeal. This is your plan's own review. Submit it in writing before the deadline on your letter, usually 180 days from the denial. Include your provider's notes showing why the care is needed. If you want to see how internal and external reviews differ, the four types of insurance appeals breaks each one down.
- Raise a parity complaint. If the denial looks like the plan treats mental health worse than physical care, file a parity complaint with your state insurance regulator. Say plainly that you believe the plan violated the Mental Health Parity and Addiction Equity Act. State insurance departments serve as the front line for MHPAEA enforcement. A complaint can trigger a closer look at the plan's practices.
Here's a quick example. Your plan approved six therapy sessions, then denied the seventh as "not medically necessary." Meanwhile, it covers unlimited physical therapy visits for a back injury. That difference is the heart of a parity complaint. You're not asking for a favor. You're pointing to a rule the plan has to follow.
Frequently asked questions
Can I appeal if I saw an out-of-network therapist?
Yes. If your plan's network had no available provider, that's a strong point for your appeal. Note every in-network provider you called who couldn't see you, with dates. Submit that list with your appeal to show the network couldn't meet your need.
How long do I have to appeal a denied psychiatry claim?
Usually 180 days from the date on your denial letter, though your plan sets the exact deadline. Find the date on the letter and count forward from there. File in writing before that day, and keep a copy of everything you send.
What is a mental health parity complaint?
It's a formal report to your state insurance regulator saying your plan treats mental health coverage worse than physical health coverage. You can file one alongside your appeal. Name the Mental Health Parity and Addiction Equity Act and describe the specific difference you found.
Does insurance have to cover therapy?
Not every plan must cover it, but most do. When a plan covers mental health, parity law limits how much harder it can make that care to use. Check your Summary of Benefits for behavioral health, then compare those limits to your medical benefits.
Your next step
Do one thing today. Pull out your last denial letter or Explanation of Benefits and write down the exact denial reason, word for word. That single line decides which appeal you file and what evidence you need.
From there, you don't have to handle the rest alone. Turnout works through the appeal with you, from reading the criteria to filing the parity complaint, so you can put your attention back on care. If you want to learn more about coverage for mental health care, start there.
